What temperature kelvin does water boil?
It depends on the absolute pressure. At one atmosphere, that would be 373 K.
What is the zero point on the absolute scale defined as?
SZero point in the absolute scale is the temperature at which the kinetic energy of the molecule becomes Zero. For a constant pressure volume would become zero and at constant volume pressure would become zero at this absolute zero temperature.
State and explain how the boiling point of water will change if the atmospheric pressure falls?
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
How much does the pressure of a gas in a rigid vessel decrease when the temperature is decreased by 1 C?
Ideal gas law: "PV = nRT"rearranged: "P = (nR/V) * T"therefore: "P is proportional to T if n,R,V are constant"P = pressureV = volumen = amount of gas substanceR = gas constantT = absolute temperature (in kelvin)It is possible to say that if the temperature decrease by a certain percentage, the pressure would also decrease by the same percentage, because the two quantities are proportional. However, to know the absolute decrease in pressure due to an absolute decrease in temperature (ΔP = -?, given ΔT = -1°C), you would need to know more information, such as the initial values of P and T.
Is it possible that water could become a solid without the aid of temperature?
Yes it is. If you increase the pressure enough, you could in theory turn water into ice, without changing the temperature. It would, however, have to be close to 0 degrees anyhow. I'm not completely sure of this info, someone could confirm?

How much does water expand at 500 degrees?
That depends on what temperature it started at. Whatever scale of temperature you are using, water will be steam at 500 degrees.
What is the zero point on the absolute scale defined as?
SZero point in the absolute scale is the temperature at which the kinetic energy of the molecule becomes Zero. For a constant pressure volume would become zero and at constant volume pressure would become zero at this absolute zero temperature.
What is the square root of of the speed of water molocules at a temperature of absolute zero?
sqrt(0) = 0 ===============What would you think it would be at absolute zero?
What would be the pressure in mm Hg if this gas was allowed to expand to 975 ml at a constant temperature?
This cannot be answered without an initial volume or pressure. But the final pressure of an expansion of a gas can be determined by the following formula. PV/T = P'V'/T' where P = pressure absolute V = volume T = temperature absolute ( ' ) indicates the new pressure, volume and temperature because the temperature is constant this can be reduced to PV = P'V' or P' = PV/V'
A cylinder pf gas at room temperature has a pressure of p1. To what temperature Celsius would the temperature have to be increased for the pressure to be 2.2p1?
It would have to be increased to 2.2 times absolute room temperature.Absolute room temperature is about 20°C, or about 293K.(2.2) x (293) = 644.6K or 371.6°C . (about 701°F.)
What is the lowest temperature and what happens at that temperature?
The lowest temperature is known as absolute zero which is equal to 0K (0 Kelvin) and -273.15 Celsius (-459.67F). Absolute zero has never been recorded but is the theoretical temperature of which no heat can be extracted from a system. It is theoretical because at 0K matter would have no pressure and therefore no volume.

What is the relation between pressure and temperature?
In general, when you have a system at a constant volume, pressure will increaseas you increase its temperature. In the particular case of an ideal gas where the relation between pressure P, absolute temperature T and volume V is given byPV =nRT(where n is moles and R the Universal Gas Constant), pressure is directly proportional to the absolute temperatureof the gas.Temperature and pressure are very much inter-related via the Ideal Gas LawPV=nRTThe major different would be that Temperature is a measurement of kinetic energy, while pressure is measurement of force per unit area.
Why would the pressure be 0 for absolutle zero?
The pressure of a gas is exerted on the walls of its container by the movement of the molecules making up the gas. The higher the temperature, the faster the particles move, increasing the pressure exerted on the sides of the container. As the temperature decreases, the movement of the gas particles slows down, reducing the pressure. At absolute zero, the gas particles would be completely frozen so that no particles would be hitting the sides of the container and the pressure exerted by the gas would be zero. This is all theoretical since absolute zero cannot yet be reached, and gas would not actually be able to have a pressure of zero.
How does vapour pressure of supercooled water compare with that of ice at the same temperature?
It would be lower.
What effects would lower the temperature at absolute zero have on brownian motion?
You cannot lower the temperature if you are at absolute zero.
